night sweats?

Hi all! I had my first baby almost three weeks ago. For the past week I've woken up in the middle of the night drenched in sweat. To the point where I didn't know my body could sweat that much! The first time it happened I was so out of it I thought I had my baby on my chest and he peed on me. (Don't worry, he doesn't sleep with mom or dad, just my first thought when I was half asleep). I had to grab a washcloth to wipe myself off because I was so sweaty! I know your hormones are going crazy trying to get back to normal, but is this normal?
